This replaces the link meta attributes with a pkgid attribute and uses a hash
of this as the crate hash. This makes the crate hash computable by things
other than the Rust compiler. It also switches the hash function ot SHA1 since
that is much more likely to be available in shell, Python, etc than SipHash.
Fixes#10188, #8523.
Rename {struct-update,fsu}-moves-and-copies, since win32
failed to run the test since UAC prevents any executable whose
name contaning "update". (#10452)
Some tests related to #9205 are expected to fail on gcc 4.8,
so they are marked as `xfail-win32` instead of `xfail-fast`.
Some tests using `extra::tempfile` fail on win32 due to #10462.
Mark them as `xfail-win32`.
When re-exporting a trait/structure/enum, then we need to propagate the
reachability of the type through the methods that are defined on it.
